Production area The highest hilly areas most suited to sparkling wine production in Trentino - hillsides surrounding Trento, Brentonico plateau and the Lakes valley. Loose, not so deep soils made of volcanic, fluvial and glacial deposits

Vinification The grapes are collected in special small crates, vinified using the method for white wine and matured in stainless steel tanks and barriques. The secondary fermentation in the bottle is followed by a period of at least 48 months on the lees. Dégorgement is then carried out.
